TODO:
* Only clone (Japan) works
* Wanted: 317-0061 FD1094 CPUs

WIP:
- 0.143u8: Kanikani added I/O board read routine to Ace Attacker and changed game to use analog device.
- 0.133u1: Renamed (aceattaa) to (aceattaca).
- 0.129: Aaron Giles fixed interger overflow in Ace Attacker.

- 0.115u4: Barry Gemma fixed inputs in Ace Attacker. Replaced 8-way Joystick with Dial, Trackball and 10x buttons. Added dipswitches 'Starting Points' and 4x 'Unknown'.
- 0.108u3: Fixed sound1 rom loading in clone (Japan, System 16A, FD1094 317-0060).
- 0.107u4: Changed description to 'Ace Attacker (FD1094 317-0059)' and clone to 'Ace Attacker (Japan, System 16A, FD1094 317-0060)'.
- 0.107u3: Arzeno Fabrice added clone Ace Attacker (System 16A, FD1094 317-0060). The FD1094 CPU came from a System 16B PCB. Changed parent description to 'Ace Attacker (FD1094 317-unknown)'.
- 6th August 2006: David Haywood - When the CPU key to Sega's Ace Attacker was dumped, probably over a year ago, we thought that it was a bad dump. The key was found on a System16B board, with System16B program roms. Today Arzeno Fabrice dumped a System16A version of the game, and to our surprise the number on the CPU was the same as the one dumped for the System16B version of the game (317-0060). Sega don't usually use the same CPU between different revisions of a game, so this was a rather odd finding. Anyway, to cut the story short I plugged Arzeno's new dump into MAME, and tried using the old CPU key dumped from the System16B board, and it worked! So why was the System16A CPU found on a System16B board? I guess nobody can really answer that, maybe a failed attempt to repair it? It will probably just go down as one of those unsolved mysteries. I haven't mapped the inputs yet, so I can't say if it's 100% playable, but the attract mode runs fine.
- 0.100u4: Changed description to 'Ace Attacker (FD1094 317-0060)'. Added 317-0060.key and new cpu1 rom ($0).
- 0.95: Fixed rom names.
- 0.91u2: Fixed cpu2 roms addresses ($20000, 30000, 40000).
- 0.88u6: Changed description to 'Ace Attacker (FD1094 317-unknown)'. Added uPD7759 sound. Changed Z80 CPU2 clock speed to 5MHz and palettesize to 6144 colors. Fixed gfx2 rom loading.
- 0.80u2: Changed Z80 CPU2 clock speed to 4MHz, replaced 2x YM3438 and RF5C68 sound with YM2151 (4MHz) and removed dipswitches.
- 18th March 2004: Charles MacDonald moved Ace Attacker to System16 driver, it's not a System 18 game.
- 0.74u2: Added Ace Attacker (Sega 1988).
- 0.36b2: Andrew Prime added Ace Attacker (Testdriver).
